Altronix EFLOW4NB 12VDC or 24VDC @ 4 amp BOARD

Altronix EFLOW4NB 12VDC or 24VDC @ 4 amp BOARD Altronix eFlow4NB UL Listed Sub-Assembly power supply/charger converts 120VAC, 60Hz input into a single 12VDC or 24VDC Class 2 Rated power-limited output. It also offers a suite of features that includes fire alarm disconnect, overvoltage protection, and low power disconnect which prevents deep discharge of stand-by batteries. Input Rating Input 120VAC 60Hz, 3.5A. Output Class 2 Rated power-limited output. 12VDC or 24VDC selectable output. 4A continuous supply current. Aux. Class 2 Rated power-limited output rated @ 1A (unswitched). Overvoltage protection. Filtered and electronically regulated outputs. Battery Charging Built-in charger for sealed lead acid or gel type batteries. Automatic switch over to stand-by battery when AC fails. Transfer to stand-by battery power is instantaneous with no interruption. (Batteries are sold separately). Fire Alarm Disconnect Supervised Fire Alarm disconnect (latching or non latching) 10K EOL resistor. Operates on a normally open (NO) or normally closed (NC) trigger. Supervision AC fail supervision (form "C" contacts). Notification trigger is selectable for 30 seconds (factory set) or 2 hours. Battery fail & presence supervision (form "C" contacts). Low power shutdown. Shuts down DC output terminals if battery voltage drops below 71-73% for 12V units and 70-75% for 24V units (depending on the power supply). Prevents deep battery discharge. Electrical Temperature: Operating: 0° C to 49° C (32° F to 120° F). Storage: - 20° C to 70° C ( - 4° F to 158° F). Relative Humidity: 85% +/- 5%. BTU/Hr. (approx.): 12VDC: 25 BTU/Hr. 24VDC: 49 BTU/Hr. Visual Indicators Green AC Power LED indicates 120VAC present. AC input and DC output LED indicators. Additional Features Short circuit and overload protection.
